I'm on Redacted and all of the bands you mentioned are there with several albums each, except "Wolfkhan". I did a quick search and there are 18,050 torrents with the tag "black.metal". A good selection, it seems.

They both use gazelle so yes you can search by tag which is essentially the music style or type. As for freelech, apollo had extensive freeleech when it first opened but redacted on the other hand never had. Both trackers use freeleech tokens for each user lately instead of global freeleech
